JULIUS J'.. SCHUIBERT, OF ST. PAUL, MINNESOTA.

STORM-SASI-I FASTENER.

Application filed March 3, 1915.

- To all whom it may concern:

Be it known that I, JULIUS J. SOHUBERT, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented a new and useful Improvement in Storm-Sash Fasteners,

of which the following is a specification.

This .invention relates to improvements in fasteners for storm sashes,its object being to provide improved means for holding swinging windowsashes, doors and shutters in closed position or in selected openposition, so that said sashes can be manipulated easily and-held firmlyagainst displacement without impeding the operation of inside windows.

Further objects of my invention will be apparent from the followingdescription, and to these ends my invention, comprises the features ofconstruction and combinations of parts, which are hereinafter moreparticularly described and claimed.

In the accompanying drawing forming part of this specification, Figure 1is a vertical section of a window frame and swinging storm sash fittedwith my improved fastening, the sash being illustrated in partly openposition; Fig. 2 is a View of a detail illustrating the sash held by myimproved fastener in fully open position; Fig. 3 is a view of a detailillustrating the swinging sash in closed position; Fig. 4 is a side viewof a detail of my improved fastener; Fig. 5 is an edge view partly insection of a detail of my improved fastener; Fig. 6 is a section of Fig.4, taken on the line XX; Fig. 7 is a side view of a detail of myimproved fastener illustrated in interlocking connection with what Iterm the lock element, which is applied to the window casing when thewindow is in partly open position, and Fig. 8 is a perspective view ofsaid fastener comprises a brace made in three longitudinal sections 5, 6and 7 plvoted to- Specification of Letters Patent.

gether, such as by rivets or other fasteners 8 and 8. One end of thisbrace is secured by a hinged connection 9 to the storm sash, saidconnection consisting of a plate having a flange 10 to which the outerend of the section 5 of the brace is pivotally fastened by a rivet 11 orother suitable means. The plate 9 is attached to the storm sash such asby screws 12 or other suitable means. Secured to a portion of the windowframe at one side and outside of the inside window sashes 2 and 3 is alock element 15, which is a plate formed with an upper shoulder 16 and alower front shoulder 17, said shoulders being adapted to cooperate withthe brace to form an interlocking connection therewith, and hold thestorm sash in either closed or partly or fully open position.

The lower front shoulder 17 is formed with a groove 18, in which thebody portion of either of the sections 5 and 6 is held laterally, saidsections being notched at 19 and 20, near their ends farthest away fromthe storm sash, said notches in said members 5 and 6 being adapted toengage the lower front shoulder to hold the storm sash in partly orfully open position.

WVhen the storm sash is in partly open position as illustrated in Fig.1, the member 6 is turned down into vertical position, and its upper endengages below the shoulder 16 to prevent the member 5 moving upwardlywith its notch out of engagement with the lower front shoulder 17. Themember 6 also engages immediately back of the lower front shoulder toprevent outward movement of the storm sash. The notch 19 in member 5,while the parts are thus interlocked, prevents the storm sash fromclosing. The parts in the position thus assumed are held until the arm 6is purposely turned upwardly with its upper end thrown forward out ofengagement from below the shoulder 16. The brace can then be disengagedfrom the shoulder 17 and moved outwardly or inwardly to adjust the stormsash as desired. When the storm sash is closed, the entire brace isswung downwardly behind the shoulder 17 and is engaged back of a pin 21driven into the side of the window casing, in which position the braceis held outside of the sash 3 and the storm sash locked against opening.The end of member 6 adjoining the rivet 8 is extended as illustratedbeyond the pivot point to assist in forming the interlocking connectionbe low the shoulder 16 as illustrated in Fig. 1,

and this extension is engaged by a slip clip or collar 22, which slidesfreely upon the member 5 over the extended portion of member 6 to form arigid interlocking joint at the pivot connection, thereby preventing thebrace from folding when the storm sash is closed and the brace engagedover the pin 21.

The lock member 15 is secured to the window casing, such as by screws 23or other suitable means, outside of the inner window sash 3 and all ofthe parts of the fastener are confined within the space lying betweenthe storm sash B and the inner window sashes 2 and 3. WVhen the stormsash is fully open, the clip 22 engages member 6 and holds the partsrigidly in straight position and member 6 is engaged by its notch 20with the lower front shoulder 17 while member 6 lies in the groove 18 inthe lower front shoulder 17. Vhile thus engaged, the longitudinallydisposed member 7, which is pivotally attached by the rivet 8 or othersuitable means to the free end of member 6 is turned into verticalposition with one of its ends engaged below the shoulder 16, and itsfront facing edge 27 engaged back of the lower front shoulder 17 asillustrated in Fig. 2. In this manner an interlocking connection,somewhat similar to the construction of interlocking connection formedby members 5 and 6 for holding the storm sash in partly open position isproduced, the only difference being that the interlocking connection,which is assisted in being formed by member 7 is adapted for holding thestorm sash in wide open position. This form of interlocking connectionis substantial and prevents the storm sash from rattling or freeingitself and blowing open or closed.

When desired a spring joint connection for holding the members 5 and 6in rigid straight position can be produced by constructing the clip 22with a lug 28, which eX- tends inwardly into a longitudinal slot 29, inmember 5, saidlug being engaged by the compression spring 30 lying insaid slot and pressing against said lug, thus urging the clip forwardly.In this manner the clip is adapted to remain engaged over the ad jacentend of member'6 to interlock members 5 and 6 together, unless the clipis intentionally moved to disengage and free'ithe members. One end ofthe clip 22 is formed with a projecting stop member 31, which strikesagainst the lower front shoulder 17 to disengage the sleeve from member6 and allow said member 6 to be swung down. By pressing against saidshoulder in the manner stated, the clip also tends to prevent the member5 from becoming disengaged from said lower front shoulder until theGopies of this patent may be obtained for member 6 is swung backwardlyout of engagement with the upper shoulder 16.

In accordance with the patent statutes,

I have described the principles of operation p v of my inventiontogether with the appara,

Having described my invention what'I I claim as new and desire toprotect by Letters Patent is 1. In combination with a window casing andswinging sash, a stay consisting 6f an arm hinged by one end to said"sash and formed with a shoulder on its otherend, a

lock member attached to said casing having upper and lower shouldersspaced apart, said arm engaging by its shoulder the lower shoulder ofsaid lock member to support said sash in open position and adapted to aswing down behind said lower shoulder to hold the sash closed, and amember pivoted upon the lnner end of sald arm and engaging below saidupper shoulder and behind said lower shoulder-on said lock member toassist in holding said arm engaged with said lock member while the sashis in open position. 5

2. In combination with a window casing and swinging sash, a staypivotally' attached by one end to said sash consisting of a plurality oflongitudinal arms hinged together near their ends, the end of one armadjoining its hinged connection to its adjacent arm overlapping aportion of the body of said adjacent arm when said arms are extended, alock member attached to said casing having an upper shoulder and a lowershoulder spaced from the upper shoulder, said arms constituting saidstay being formed with shoulders near their ends farthest away from saidsash adapted to engage said lower shoulder to assist in either holdingthe sash in partly or fully open position and said overlapping portionbeing adapted to engage below said upper shoulder while the shoulder onthe adjoining arm engages said lower shoulder to hold said stay withsaid sash in partly open position, and means on said stay engaging saidoverlapping end to hold said arms extended.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
